FILTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 612,976, dated October25, 1898. Application filed October 15I 1897. Serial No. 655,276. (Nomodell.)

To all whom it may concern.-

Be it known that I, EDWARD L. POWELL, a citizen of the United States,residing ,at At-l lantic Highlands, in the county of Monmouth and Stateof New Jersey, have invented certain new and useful Improvements inFiltering Apparatus and I do hereby declare the following to be a full,clear, andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for removing impurities fromliquids, and particularly to suoli apparatus adapted to be connectedwith the faucets of Water-supply pipes used to furnish water fordrinking and culinary purposes, and some of the objects of thisinvention are to provide a simple, cheap, and effective apparatus ofthis character which can be readily attached to and detached from theordinary faucets of watersupply pipes and also which when so i connectedmay be used as a filter or may be thrown out of use while still inposition `upon the faucet, and, furthermore, to provide a filteringapparatus capable of long service and having renewable parts, which canbe readily inserted; and with these and other objects in view theinvention consists substantially of the construction, combination, andarrangement of parts, hereinafter more fully described in thespecification and illustrated in the accompanying drawings, in whichFigure 1 is a side elevation, partly broken away, of my improvedfiltering apparatus, showing the connection for the faucet in section.Fig. 2 is an edge View of the same when the filter is not in use, alsoshowing the faucet connection in section. Fig. 3 is a sectional viewshowing the interior construction of the parts. Fig. 4 shows a modifiedform of clamping device, and Figs. 5 and 6 illustrate still other formsof the clamping devices.

Similar characters of reference designate like parts throughout theseveral views.

Referring to the drawings, and particularly to the construction shown inFigs. l, 2, and 3 thereof, the numeral 1 designates a filter constructedin accordance with my improvements, consisting of a conical back portion2,

l provided with an induction or supply tube 3,

communicating with the interior thereof, as shown in Fig. 1, and formedon or connected to the interior concave face or side of the back portion2 are radial vanes or ribs 4, extending outwardly from a solid shank orscrew-threaded projection 5, projecting vertically from the center ofthe concave face or side of the back portion, and the inner lowerportions of the ribs 4 around the base of the shank 5 are preferablyprovided with ports or openings 6, and, if desired, the shank 5 may havesecured thereon a washer-7.

The front portion 8` of the filter is provided with a central opening 9,with which communicates a tubular extension 10, provided with lateralports or openings 11, and from the extension 10 project radial ribs orvanes 12, provided 'adjacent to their connection with said extensionwith ports or openin gs 13, and secured to the inner face or rim of thefront portion is a perforated screen or similar de vice 14, having acentral opening 15, registering with the bore of the tubular extension10, and the front portion 8 is preferably provided with an inwardlydirected annular flange or rim 16 to inclose the periphery of the backportion when the parts are connected. Secured on the shank 5 are disks17, of filter-paper or any other suitable material, over which is placedthe front portion of the filter, and also upon said shank 5 is removablysecureda discharge-nozzle 18, having a depending spout 19 and aright-angled tubular eX- tension 20, provided with lateral ports oropenings 2l and having a screw-threaded interior adapted to receive thescrew-threaded extremity of the shank 5, whereby the front and backparts of the filter are detachably connected. The foregoing constructionconstitutes the main and essential features of my invention; but I may,if desired, employ-other means for detachably connecting the front andback portions of the iilter--as, for instance, the construction shown inFig. 4, in `which I employ a clamping-yoke 25, `the ends of which engagethe inlet-tube 26 and a diametrically opposite lug or projection 27,said yoke being provided with a central set-screw or clan1p-28 of anypreferred construction, and when this IOO clamp is employed the frontportion will be provided with an eccentric discharge-spout 29.

In Fig. I have shown detachable clamps 30, provided with set-screws 31,adapted to engage the annular horizont-al flanges 32 and 33 on the frontand back portions 34 and 35, respectively, of the filter, and in thisconstruction a discharge-spout 36 of any preferred form is employed.

Still another construction for connecting the front and back portions 37and 38, respectively, of the filter is illustrated in Fig. 6, in whichthe back portion 38 is provided with a plurality of sets of peripherallugs or yokes 39 and a slotted lug 40, while the front portion carriesperipheral lugs 40 and 4l, the former being adapted to be pivotallysecured by a pin or split key 42 between the sets of lugs 39, thusforming a hinge connection for the front and back portions, and the lug4l carries a clamping-screw 43, which engages the slotted lug 40, aswill be understood.

I do not confine myself to any specific forms of clamping means hereinshown and described, as I may use that construction which is foundpreferable in practice and which is best adapted for the purpose.

My improved coupling or connectionv employed in attaching the filter toa faucet of a Water-supply pipe consists of a casting or coupling 50,provided with a central vertical bore 51, the upper end whereof isenlarged and the inner walls of which are screw-threaded to affordattachment with the faucet of the water-supply pipe, and, if desired,the outer rim thereof may be provided with a plurality of iiattenedfaces 52, adapted to receive a wrench or other instrument used inconnecting and disconnecting the coupling, and the opposite end of saidbore is provided with a tubular discharge-opening 53.

Movably mounted in the tubular extension 54 of the coupling is a sleeve55, having a transverse opening 56 therein, adapted to register with thevertical bore 51 of the casting or coupling when the sleeve is turned toa predetermined position, and this sleeve is provided With a by-passpassage or way 56a, communicating with the centralinteriorly-screwthreaded opening 57 thereof and with the vertical bore5l of the coupling 50 when the sleeve is turned in the proper position,and the extremity of this sleeve is preferably solid and is retained inposition by a screw or similar device 58, and the tubular extension ofthe coupling is preferably cut away to form a segmental recess or notch59, in which the stoppin 60, carried by a sleeve, operates so that themovement of the latter can be regulated.

I may employ my improved filter herein described with or without thecoupling before mentioned; but I prefer to use this coupling to formconnection with the faucet of the water-supply pipe unless theconstruction of the faucet prevents the employment of the couping.

I do not desire to confine myself to the specie construction,combination, and arrangement of parts herein shown and described, and Itherefore reserve the right to make all changes in and modications ofthe same as fairly come within the scope of myinvention.

Having now accurately described my invention, what Iclaim as new, anddesire to secure by Letters Patent, is-
